What type of reproduction involves forming offspring from two
parents?
a Asexual
b Sexual
C Mitosis
int?
d Replication

Answers

Answer:

Sexual

Explanation:

Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.

Hope it helps

Answer: Sexual, I believe.

Explanation:

If it were Asexual, it'd only involve one parent. Mitosis has daughter cells have the same number of chromosomes as parent cells (heavy emphasis on cells as in plural cells.) And replication is just copying a cell.

“Explain how chemical energy for use in the cell is generated by electron transport and chemiosmosis”
PLEASE HELP!!
*50 points to whoever can answer that question and draw a flowchart, thank you*

Answers

Answer: The ETC is the last part of cellular respiration. In the first steps of cellular respiration (glycolysis and Krebs cylce), electrons are freed from glucose derived molecules.  In the ETC the electrons are passed on through a series of proteins in the inner membrane of the mitochondria. The electrons in a sense 'flow' to lower energy levels (see image), they lose energy in the process.

Energy produced by H+ travelling via ATP synthase and down a concentration gradient is used by chemiosmosis. ADP is phosphorylated with this energy to create ATP.

What is Chemiosmosis?

Chemiosmosis is the passage of ions along their electrochemical gradient through a semipermeable transmembrane domain structure. Adenosine triphosphate is created when hydrogen ions pass a membrane during photosynthesis or cellular respiration. This is a significant example.

The process of ions (often H+ ions, commonly referred to as protons) diffusing across a membrane that is selectively permeable is known as chemiosmosis. Chemiosmosis produces a concentration gradient of a diffusing ion from across membrane, similar to osmosis. Potential energy that can perform work is present in concentration gradients.

Thus, energy produced by H+ travelling via ATP synthase and down a concentration gradient is used by chemiosmosis. ADP is phosphorylated with this energy to create ATP.

Answer:

Translation I believe

Explanation:

Learning Competencies: 1. Explain how protein is made using information from DNA. 2. Explain how mutation may cause changes in the structure and function of a protein

Answers

Answer:

The correct answer is -

1. protein synthesis or central dogma

2. leads to changes in the structure by changing in the codes which results in a decrease or loss of function.

Explanation:

1, Protein is made from the information coded in DNA base sequences by the two process protein synthesis that is also called central dogma. The two-process involve in this are transcription involves encoding the information present in DNA by mRNA molecule that codes the information in complementary sequence to DNA. which is then moved out of the nucleus and perform the translation with help of tRNA and ribosome to code the amino acid with help of triplet codes present in mRNA. These amino acids chain are called proteins.

2. Mutations can lead to change in the base sequences or deletion of the base which affects the structure of the protein and also leads to changes in an encoded protein or to a decrease or complete loss in its function or expression. Mutation can damage the cell or organism as it affects the gene expression of all cells of organisms.

how do you know when a surface has produced more friction​

Answers

Answer:

Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force.

The amount of energy available in the form of nonrenewable resources is finite. You can personally make a difference in making sure that the world continues to have enough energy to supply electricity to everyone who needs it. Today’s assignment is an opportunity to do research into ways that you can make an impact.

Your research will focus on creating a plan that you want to present to one of the following:
your family
a club or team that you are a part of
a community organization like your church or school

The purpose of your plan is to see the world’s energy last a long time. There are a couple of categories to consider, such as different ways to do the following things:
Use renewable resources (example: adding solar panels to a building)
Conserve energy (example: reducing the amount of electricity used)
Reduce, reuse, and recycle (example: planning a recycling drive)
Add “green spaces” (example: growing vegetables in a garden)

Q.2. Describe the different phases of meiotic prophase – I. Mention the chromosomal events during each stage.

Prophase-I occurs over a long duration and involves several complicated changes in meiotic cell division. It is important because genetic recombineiion and variation in sexually reproducing organism occurs due to the events of this phase.

EXPLANATION:

Leptotene

➥ The chromatin network opens out and threads become clear.

➥ The chromosomes are thin, slender and long.

➥ Chromosome number is diploid.

Zygotene

➥ Corresponding chromosomes become intimately associated.

➥ The process of pairing is known as synapse. It is so exact that pairing is not merely between corresponding chromosomes but between corresponding individual units.

➥ The chromosomes become shorter and thicker.

Pachytene or Pachynema

➥ The synaptic chromosomes become very intimately associated.

➥ The pair of chromosomes becomes short and thick.

➥ Crossing over occurs at this stage. Chiasmata are clearly seen.

Diplotene

➥ Homologous chromosomes start separating from one another.

➥ Chiasmata tend to slip out of the chromosomes. This is known as terminalisation of chiasmata.

➥ Chromosomes start separating out but the separation is not complete.

➥ Nuclear membrane and nucleolus start disappearing.

Diakinesis

➥ The bivalents condense further and get randomly distributed.

➥ The separation of paired chromosomes is almost complete.

➥ Terminalisation of chiasmata is almost complete.

➥ Nuclear membrane and nucleolus disappear.

The difference between pinocytosis and receptor-mediated endocytosis is that _____. Question 14 options: pinocytosis can concentrate substances from the extracellular fluid, but receptor-mediated endocytosis cannot. pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis offers more selectivity. pinocytosis brings only water molecules into the cell, but receptor-mediated endocytosis brings in other molecules as well. pinocytosis increases the surface area of the plasma membrane, whereas receptor-mediated endocytosis decreases the plasma membrane surface area.

Answers

Answer:

The difference between pinocytosis and receptor-mediated endocytosis is that pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis offers more selectivity.

Explanation:

Pinocytosis and receptor-mediated endocytosis are two types of endocytosis.

The first one consists of plasmatic membrane invaginations that capture extracellular fluid with different nutrients and sends it to the inside of the cell in vesicles. The second one, receptor-mediated endocytosis, consists of receptors on the outside of the plasmatic membrane and clathrin proteins on the interior side of the membrane. When the receptors are in contact with its specific molecule, a vesicle surrounded by clathrin proteins, is formed transporting specific molecules to the cell's interior.

Why are organisms that reproduce sexually less likely to accumulate deleterious mutations ?
